Morgan Keyanna Martin, who is four months pregnant, has been missing for nearly two weeks.

She was last seen walking out the front door of her home at 2808 17th Ave. S to meet someone to whom she had been speaking on her cellphone, family members said.

Martin, who is 5 feet 2, 175 pounds and of mixed race, has black hair and brown eyes. She was wearing a white tank top, a pink jacket with fur around the hood, gray bottoms and fuzzy pink slippers the night of her disappearance.

St. Petersburg Police officials have called the case alarming, noting Martin had only a cellphone when she vanished.

"Given all the property she left behind, she didn't appear to be in a position to just leave on her own," said police spokesman Mike Puetz. "That's not typical of a person who runs away from home."

Anyone with information about the girl can call police at (727) 893-7780.
